Setting CubeMX ioc to be similar to STM32F4 template - remember to update HEAP size

/**
******************************************************************************
* @file startup_stm32l496xx.s
* @author MCD Application Team
* @brief STM32L496xx devices vector table GCC toolchain.
* This module performs:
* - Set the initial SP
* - Set the initial PC == Reset_Handler,
* - Set the vector table entries with the exceptions ISR address,
* - Configure the clock system
* - Branches to main in the C library (which eventually
* calls main()).
* After Reset the Cortex-M4 processor is in Thread mode,
* priority is Privileged, and the Stack is set to Main.
